If the battery black wire connects to the ring on the jack socket, (as in your picture) then this is impossible - check your wiring - perhaps you have the earth and ring connections vice versa in the jack bajaman

Just for future reference I have had this happen with bad battery clips, with those cheap plastic ones they get squashed and I assume the red and black leads connect inside as squeezing it can allow the LED to come on even when wired correctly.

i noticed this happened as well after i fixed the wiring...as im using small enclosures. problem was solved getting a T- styled battery clip...

ive learnt so much about making/mounting/wiring up pedals from just 3 pedal builds.

the wiring etc is pretty simple (even an idiot like me can sorta get a graps like it) but i think making a gig worthy professional pedal is an art itself.
